Odd.  I've seen something like this many years ago, with rather old 
versions of Scala, but it did not happen recently.

What is the result of "isabelle getenv SCALA_HOME"?

To make double sure: can you delete ISABELLE_HOME/lib/classes/Pure.jar and 
try again?  Or try "isabelle jedit -bf".


In principle, this should all work routinely.  I am building from 
repository myself with Windows 2008, Windows 7, Windows 8.1, Windows 10.
